f7 l y @M7/)Jima Patented May 28, 1946 UNITED STATES PATENT OFFICE VALVE I `Eugene Si Arnold, Cleveland, Ohio v `Appena-tion March' s, 1945, serial No. 581,257 e claims. rc1'. 251-137) This invention relates to improvements in valves, primarily to faucet valves, but the improved valve constructionaccording to the present invention can also be used for steam, oil', air,

and gas valves as well as for controlling chemi fluid controlled by the valve for tightening its clo-t sure mechanisms since ,it 'works with the pressure of the fluid, not against it, as will be eX- plained more fully hereinafterV in the ,description;

Another object of the present invention is the provision of a valve of the character described which will prevent any grit and foreign matter in the liquid from lodging on surfaces of the valve seat and on other tightening means, sothat leaks are practically impossible;

Still another object of the present invention is the provision of an improved valve which is adapted for direct connection to the water supply main irrespective of the pressure therein which is simple and robust in construction, and since it has the minimum number of moving parts consequently needs little or no attention over long periods of service.

Further objects of the instant invention reside in any novel feature of construction or operation or novel combination of parts present in the embodiment of the invention described and shown in the accompanying drawing whether within or without the scope of the appended claims and irrespective of other specific statements as to the scope of the invention contained herein.

In the drawing:

Figure 1 is a top plan view of a preferred embodiment of my invention as it appears with the outer valve casing partially broken away andl when the valve is open;

Figure 2 is a sectional view on the line 2-2 of Figure 1, showing the valve in its closed position;

Figure 3 is a cross-sectional view on the line 3-3 of Figure 2; and

Figure 4 is a cross-sectional view on the line 4-4 of Figure l.

Similar numerals refer throughout the several views. Y

In the drawing, the numeral I denotes a valve casing' which has an intake portion 2 that is connected to its outlet portion 3 by means of a tapered channel 4. 'Ihe channel 4, which tapers to similar parts at about ve degrees toward the outlet portion 3, serves as arunway for a correspondingly tapered plug 5, which closes the channel 4 when its major portion is tightly inserted into the major portion of `channel 4 as may .be V:geen in Figure 2. The plug 5 is secured to the hollow portion 6 of a movable shaft 'I which is guided by a stationaryrshaft 8, that is secured to the outlet portion 3 and that is partially extended into the hollow portion 6 of shaft 1. The bore in the hollow shaft portion 6 is so deep that it will afford sufficient end clearance to allow any fluid that may be compressed therein to drain off through a small key way 9 or the like.

A neXible, permeabley disk having a soft resilient outer periphery, preferably aflexible copper wir@ mesh disk In having a. soft rubberedge is attachedv to the outer extremity of the hollow portion 6 of the movable shaft 1, so that the channel runway 4 will be ycleaned at each reciprocating movement of the shaft 1 and of the plug 5. Likewise, a flexible permeable collar having a soft resilient inner periphery, preferably a flexible copper wire mesh screen collar I2 having a soft inner rubber edge I4, is secured to the interior of casing I near the wider opening of channel 4. The soft edge I4 encompasses and rests against the outer surface of plug 5, so that the plug 5 will `be cleaned at each opening or closingmovement- This cleansing action of the soft edges II and I4 will prevent the lodging of grit and foreign matter on the surface of the plug `5 and of the channel runway 4 respectively, thus insuring absolute tightness of the closed valve at all times.

The reciprocation or the opening and closing movement of the shaft I and of the plug 5 can be caused by any suitable means the details of which will depend upon the purpose for which a particular valve is intended. In the case of a faucet valve as shown in the drawing, I prefer to extend the solid portion of shaft l through a packing 20 in a Wall 2|, which separates the major portion of the interior of casing I from a compartment 22; a bell crank lever 23 having slotted arms 24 and 25 is pivotally secured at 21 in the compartment 22, and the slotted arms 24 and 25 engage pins 28 and 29 respectively; pin 28 is carried by the outer extremity of the solid portion of shaft 1, and -pin 29 is carried by a push rod 30 which extends through the outer wall of compartment 22; a spring 3| tends to hold the rod 30, lever 23, shaft 'I and plug 5 in the closed position shown in Fig. 2. If rod 30 is pressed inwardly, the lever 23 will be in the Fig. 2, and the valve will be open as shown in Fig. 1. If the manual pressure is released from rod 30, the parts 5, 1, 23, and 30 will move back to the closed position and the pressure of the fluid will aid in pressing the plug 5 tightly into the runway of channel `4. l

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification, it will be understood that variousy omissions and substitutions and changes in the form and details of the device illustrated and in its operation -V may be made by those skilled in the art without departing from the spirit of the invention. Itis the intention, therefore, to be limited only as indicated by the scope of the following claims.
